ROTARYl ENGINE.'

SPECIFICATION forming part of Letters Patent No. 276,360, dated April 24, 1883. Application tiled November 9,1882. (No model.)

To all whom it may concern: i

Be it known that I, CHARLES F. Conv, ot' South St. Louis, in the State ot Missouri, have invented acertain new and useful Improvement in Rotary Engines, of which the following is a full, clear, and exact description, reference bei ing had to the accompanying drawings, forming part of this specification.

This is an improvement on my invention on which a patentwas allowed to me on or about the th day of October, 1882.

My improvement consistsof a device for reversin g the motion of the single piston of the engine, and for the association of a number ot' these engines, together with the described means for making connection between them,y

so that the exhaust air or steam from one eugine shall drive other engine or engines connected therewith. r

Figure lis a side view of a compound engine, or two engines, illustrating my invention. Fig. 2 is a top view of saine. Fig. 3 is a section at 3 3, Fig. 2.

Two cylinders are shown at A A fixed to a bed, B. The first part of my improvement is applicable to a single piston of an engine, said part applying to the device for reversing the motion of the piston. The two cylinders are shown to illustrate the second part of my im provement, which applies to two or more engines acting together, so asto form a compound engine, the exhaust of the rst engine communicating with the slide-valve chest of the next engine, and so on through the series. The pistons of the engines may be connected by pulleys and belts, or by other means, or each engine may drive a separate machine. Where the pistons are connected the power may be taken from any one or more ot' them. The engines are shown so arranged in line that their piston shafts are parallel with each other; but the arrangement may be changed, so that the ends of the cylinders-will be parallel with each other and the piston-shafts in line coupled together, or consisting of a single pipe closed between the engines. The construction of each cylinder and piston is substantially similar to that described in the speciiication to the said application now on iile in the Patent Office, except as to the reversingjet-a valve by which the air or steam is directed to the required jetand a pipe leading from the exhaust ot one cylinder to the valvechest ot' the other.

C is the induction-pipe, through which compressed air or steam is supplied to the valvechest D of the tirst cylinder, A.

Eis the valve, which may consist of a simple sliding plate constructed to cover either one of the valve-ports F or G. i

i H is the valve stem,\vorling through a stu li'- ing-box, I, at the end of the valve-chest. This Astem is shown as extending through another stufting-box,1', and connected to the slidevalve of the second engine.

The ports F and G in the valve-seat J end within the cylinder in jet-nozzlesf and g, so inclined that the jet issuing therefrom shall turn the rotary piston in opposite directions, the construction being such that it the valveport F and jet-nozzlef are open (and the port and nozzle G g closed) the rotary piston will turn in the direction indicated by the arrow, whereas when the valve-port G and, nozzle g are open and those Ff closed the piston will rotate'in an opposite direction. As a suitable means for moving the valves, I show a lever, K, Slotted to receive a pin, fi, on the valve-stem, the lever being fulcrurned at k. The piston has wings L, extending outward from the hollow piston-shaft M. I have shown iour wings; but I do not confine myself to any particular number. Each wing has a marginal gap, Z, in line with the jets when the outer edge ot' the wing is between the nozzles. I will here say that only a single direct and single reversing nozzle is shown for each cylinder; but it is obvious that more than one of each may be used, either side by side or in different parts of the periphery of the cylinder. The piston-shaft M extends axially through the cylinder, and has an interior `chamber or chambers, m, in communication with the interior of the cylinder by holes 'm'. One or both ends of the piston-shaft extend through a stntling-box, N, having therein cham bern, communicating with the chamber m by holes m2 in the piston-shaft M. [he chamber n is in communication with the exhaust-pipe O, that extends to the valvechest of the second engine. In like manner, when there are three or more engines, the exhaust from each engine will enter the valvechest of the engine following, while the last engine or cylinder of the series may exhaust into the open air. One end of each pistonshatt extends through the stutling-box, while the othermay extend through the otherstufn gbox, or turnin a closed bearing. The projecting end of the piston-shaft carries a belt-pulley, P, to receive a belt connecting the piston-shafts, so that they will turn in unison. Where compressed air is used as a medium for driving the compound engine all the pistons may run at about equal speed, and the pulleys P may beall ofone size; butwhere steam is used todrive the engine it is obvious that the condensation of steam will cause a smaller quantity to pass through each sncceedin g cylinder than through the one preceding, so that the motion ot' the piston 'would be slower in the cylinder toward the end ofthe series. To provide for this the pulley on the shaft of each succeeding piston may be of larger diameter, as shown in Fig. 2, so that the surface speed ot' all the pulleys may be equal.

l have shown the exhaust taking place from both ends of the cylinder by two exhaustpipes, O, but the exhaust may be from one end alone, and where it is from that end of the shaft which does not carry the pulley the stuit'- ing-box may be dispensed with at that end and the exhaust be through the end of the pistonshal't into the exhaust-pipe.

In place of the slide-valve E, I may use any valve or valves that would serve to close one of the nozzlesf org and open the other one of them.

I do not claim, broadly, the use of exhauststeam from one rotary engine for the purpose of driving another rotary engine, as suggested in English provisional specification under No. 502 ot' 1864.

I claim- Y 1. The combination, with a rotary engine having a single piston constructed to rotate in either direction, of the two jets inclinedin opposite directions and adapted to discharge against a single set of piston-wings, as set forth.

2. The combination, with rotary engines each having a central exhaust and circumferential jet, of a pipe connecting the exhaust of one engine with the circumferential jet of the following, as set forth.

3. The combination ot' engines having independent shafts, eentral exhausts, pistons, jets, and pulleys, and a pipe connecting the central exhaust of one engine with the steam-jet of the next engine, as set forth.

4. The combination, with engines having independent shafts, central exhausts, pistons, and jets, of dii'erential pulleys, and a pipe connecting the central exhaust of one engine with thejet ot' the next engine, as set forth.

5. Two or more rotary engines with oppositely-inclined nozzles f and g, and having slide-valves upon a single stem, substantially as and for the purpose set forth.

In testimony of which invention I have hereunto set my hand this 1st day of November, 1882.
